Apple has released the second public beta of the upcoming OS X Yosemite, but with no word about what might have changed. If you’re running the first public beta, get the new version from the Updates tab in the App Store app. You can still sign up for the public beta, and regardless, we recommend picking up a copy of Joe Kissell’s name-your-own-price “Take Control of Beta Testing Yosemite,” which provides complete details on preparing for, installing, and testing the Yosemite beta. follow link

The Recent Items submenu in the Apple menu is handy, but what if you want to work with a file in there in the Finder, rather than open it? Just press Command when that menu is showing, and all the Applications and Documents change to "Show ... in Finder." This feature is new as of Mac OS X 10.6.3 Snow Leopard.
